FILES & SYNCHRONIZATION
Accessing your Files Using the Nextcloud Web Interface
You can access your Nextcloud files with the Nextcloud Web interface and create, preview, edit, delete, share, and
re-share files. Your Nextcloud administrator has the option to disable these features, so if any of them are missing on
your system ask your server administrator.
Tagging Files
You can assign tags to files. To create tags, open a file to the Details view. Then type your tags. To enter more than one
tag press the return key after creating each tag. All tags are system tags, and are shared by all users on your Nextcloud
server.
Then use the Tags filter on the left sidebar to filter files by tags.
Comments
Use the Details view to add and read comments on any file or folder. Comments are visible to everyone who has access
to the file.

Video Player
You can play videos in Nextcloud with the Video Player app by simply clicking on the file. Video streaming
by the native Nextcloud video player depends on your Web browser and the video format. If your Nextcloud
administrator has enabled video streaming, and it doesn’t work in your Web browser, it may be a browser
issue. See https://developer.mozilla.org/en-US/docs/Web/HTML/Supported_media_formats#Browser_compatibility
for supported multimedia formats in Web browsers.
File Controls
Nextcloud can display thumbnail previews for image files, MP3 covers, and text files, if this enabled by your server
administrator. Hover your cursor over a file or folder to expose the controls for the following operations:
Favorites Click the star to the left of the file icon to mark it as a favorite, and quickly find all of your favorites with
the Favorites filter on the left sidebar.
Share Share the file or folder with a group or other users, and create public shares with hyperlinks. You can also see
who you have shared with already, and revoke shares by clicking the trash can icon.
Note: Since version 9.0, you can see all re-shares of your original file shares.
If username auto-completion is enabled, when you start typing the user or group name Nextcloud will automatically
complete it for you. If your administrator has enabled email notifications, you can send an email notification of the
new share from the sharing screen.
You have five share permissions:
4.1. Accessing your Files Using the Nextcloud Web Interface 13
Nextcloud User Manual, Release 12
Can share; allows the users you share with to re-share.
Can edit; allows the users you share with to edit your shared files, and to collaborate using the Documents app.
Create; allows the users you share with to create new files and add them to the share.
Change; allows uploading a new version of a shared file and replacing it.
Delete; allows the users you share with to delete shared files.
Overflow Menu The Overflow menu (three dots) displays file details, and allows you to rename, download, or delete
files.
The Settings gear icon at the lower left allows you to show or hide hidden files in your Nextcloud Web interface.
These are also called dotfiles, because they are prefixed with a dot, e.g. .mailfile. The dot tells your operating
system to hide these files in your file browsers, unless you choose to display them. Usually these are configuration
files, so having the option to hide them reduces clutter.
Previewing Files
You can display uncompressed text files, OpenDocument files, videos, and image files in the Nextcloud embedded
viewers by clicking on the file name. There may be other file types you can preview if your Nextcloud administrator
has enabled them. If Nextcloud cannot display a file, it starts a download process and downloads the file to your
computer.
Navigating Inside Your Nextcloud
Navigating through folders in Nextcloud is as simple as clicking on a folder to open it and using the back button on
your browser to move to a previous level. Nextcloud also provides a navigation bar at the top of the Files field for

quick navigation.
Sharing Status Icons
Any folder that has been shared is marked with the Shared overlay icon. Public link shares are marked with a chain
link. Un-shared folders are blank.
Creating or Uploading Files and Directories
Upload or create new files or folders directly in an Nextcloud folder by clicking on the New button in the Files app.
The New button provides the following options:
Up arrow Upload files from your computer into Nextcloud. You can also upload files by dragging and dropping them
from your file manager.
Text file Creates a new text file and adds the file to your current folder.
Folder Creates a new folder in the current folder.
Selecting Files or Folders
You can select one or more files or folders by clicking on their checkboxes. To select all files in the current directory,
click on the checkbox located at the top of the files listing.
When you select multiple files, you can delete all of them, or download them as a ZIP file by using the Delete or
Download buttons that appear at the top.
4.1. Accessing your Files Using the Nextcloud Web Interface 17
Nextcloud User Manual, Release 12
Note: If the Download button is not visible, the administrator has disabled this feature.
Filtering the Files View
The left sidebar on the Files page contains several filters for quickly sorting and managing your files.
All files The default view; displays all files that you have access to.
Favorites Files or folders marked with the yellow star.
Shared with you Displays all files shared with you by another user or group.
Shared with others Displays all files that you have shared with other users or groups.
Shared by link Displays all files that are shared by you via public link.
External Storage (optional) Files that you have access to on external storage devices and services such as Dropbox,
Google, and Amazon S3.
Moving Files
You can move files and folders by dragging and dropping them into any directory.
Change in Share Expiration Date
In older versions of Nextcloud, you could set an expiration date on both local and public shares. Now you can set
an expiration date only on public shares, and local shares do not expire when public shares expire. The only way to
“expire” a local share is to click the trash can icon to un-share your files.
Creating or Connecting to a Federation Share Link
Federated Cloud Sharing allows you to mount file shares from remote Nextcloud servers, and manage them just like
a local share. In Nextcloud 9 the process for creating a new sharing link is easier and more streamlined. See Using
Federation Shares to learn to how to create and connect to new Federated Cloud shares.
Accessing Nextcloud Files Using WebDAV
Nextcloud fully supports the WebDAV protocol, and you can connect and synchronize with your Nextcloud files
over WebDAV. In this chapter you will learn how to connect Linux, macOS, Windows, and mobile devices to your
Nextcloud server via WebDAV. Before we get into configuring WebDAV, let’s take a quick look at the recommended
way of connecting client devices to your Nextcloud servers.
Nextcloud Desktop and Mobile Clients
The recommended way to synchronize a desktop PC with a Nextcloud server is by using Nextcloud/ownCloud sync
clients. You can configure the client to save files in any local directory and you can choose which directories on the
Nextcloud server to sync with. The client displays the current connection status and logs all activity, so you always
know which remote files have been downloaded to your PC and you can verify that files created and updated on your
local PC are properly synchronized with the server.
18 Chapter 4. Files & Synchronization
Nextcloud User Manual, Release 12
The recommended way to synchronize Nextcloud server with Android and Apple iOS devices is by using the mobile
apps.
To connect your mobile app to a Nextcloud server use the base URL and folder only:
example.com/nextcloud
In addition to the mobile apps provided by Nextcloud or ownCloud, you can use other apps to connect to Nextcloud
from your mobile device using WebDAV. WebDAV Navigator is a good (proprietary) app for Android devices and
iPhones. The URL to use on these is:
example.com/nextcloud/remote.php/dav/files/USERNAME/
WebDAV Configuration
If you prefer, you may also connect your desktop PC to your Nextcloud server by using the WebDAV protocol rather
than using a special client application. Web Distributed Authoring and Versioning (WebDAV) is a Hypertext Transfer
Protocol (HTTP) extension that makes it easy to create, read, and edit files on Web servers. With WebDAV you can
access your Nextcloud shares on Linux, macOS and Windows in the same way as any remote network share, and stay
synchronized.
Note: In the following examples, You must adjust example.com/ to the URL of your Nextcloud server installation.
Accessing Files Using Linux
You can access files in Linux operating systems using the following methods.
Nautilus File Manager
Use the davs:// protocol to connect the Nautilus file manager to your Nextcloud share:
davs://example.com/nextcloud/remote.php/dav/files/USERNAME/
Note: If your server connection is not HTTPS-secured, use dav:// instead of davs://.
4.2. Accessing Nextcloud Files Using WebDAV 19
Nextcloud User Manual, Release 12
Accessing Files with KDE and Dolphin File Manager
To access your Nextcloud files using the Dolphin file manager in KDE, use the webdav:// protocol:
webdav://example.com/nextcloud/remote.php/dav/files/USERNAME/
You can create a permanent link to your Nextcloud server:
1. Open Dolphin and click “Network” in the left hand “Places” column.
2. Click on the icon labeled Add a Network Folder. The resulting dialog should appear with WebDAV already
selected.
3. If WebDAV is not selected, select it.
4. Click Next.
5. Enter the following settings:
20 Chapter 4. Files & Synchronization
Nextcloud User Manual, Release 12
Name: The name you want to see in the Places bookmark, for example Nextcloud.
User: The Nextcloud username you used to log in, for example admin.
Server: The Nextcloud domain name, for example example.com (without http:// before or directories
afterwards).
Folder – Enter the path nextcloud/remote.php/dav/files/USERNAME/.
6. (Optional) Check the “Create icon checkbox” for a bookmark to appear in the Places column.
7. (Optional) Provide any special settings or an SSL certificate in the “Port & Encrypted” checkbox.
Creating WebDAV Mounts on the Linux Command Line
You can create WebDAV mounts from the Linux command line. This is useful if you prefer to access Nextcloud the
same way as any other remote filesystem mount. The following example shows how to create a personal mount and
have it mounted automatically every time you log in to your Linux computer.
1. Install the davfs2 WebDAV filesystem driver, which allows you to mount WebDAV shares just like any other
remote filesystem. Use this command to install it on Debian/Ubuntu:
apt-get install davfs2
2. Use this command to install it on CentOS, Fedora, and openSUSE:
yum install davfs2
3. Add yourself to the davfs2 group:
usermod -aG davfs2 <username>
3. Then create an nextcloud directory in your home directory for the mountpoint, and .davfs2/ for your
personal configuration file:
mkdir ~/nextcloud
mkdir ~/.davfs2
4. Copy /etc/davfs2/secrets to ~/.davfs2:
cp /etc/davfs2/secrets ~/.davfs2/secrets
5. Set yourself as the owner and make the permissions read-write owner only:
chown <username>:<username> ~/.davfs2/secrets
chmod 600 ~/.davfs2/secrets
6. Add your Nextcloud login credentials to the end of the secrets file, using your Nextcloud server URL and
your Nextcloud username and password:
example.com/nextcloud/remote.php/dav/files/USERNAME/ <username> <password>
7. Add the mount information to /etc/fstab:
example.com/nextcloud/remote.php/dav/files/USERNAME/ /home/<username>/nextcloud
davfs user,rw,auto 0 0
8. Then test that it mounts and authenticates by running the following command. If you set it up correctly you
won’t need root permissions:
4.2. Accessing Nextcloud Files Using WebDAV 21
Nextcloud User Manual, Release 12
mount ~/nextcloud
9. You should also be able to unmount it:
umount ~/nextcloud
Now every time you login to your Linux system your Nextcloud share should automatically mount via WebDAV in
your ~/nextcloud directory. If you prefer to mount it manually, change auto to noauto in /etc/fstab.
Known Issues
Problem
Resource temporarily unavailable
Solution
If you experience trouble when you create a file in the directory, edit /etc/davfs2/davfs2.conf and add:
use_locks 0
Problem
Certificate warnings
Solution
If you use a self-signed certificate, you will get a warning. To change this, you need to configure
davfs2 to recognize your certificate. Copy mycertificate.pem to /etc/davfs2/certs/. Then edit
/etc/davfs2/davfs2.conf and uncomment the line servercert. Now add the path of your certificate as in
this example:
servercert /etc/davfs2/certs/mycertificate.pem
Accessing Files Using macOS
Note: The macOS Finder suffers from a series of implementation problems and should only be used if the Nextcloud
server runs on Apache and mod_php, or Nginx 1.3.8+.
To access files through the macOS Finder:
1. Choose Go > Connect to Server.
The “Connect to Server” window opens.
2. Specify the address of the server in the Server Address field.
22 Chapter 4. Files & Synchronization
Nextcloud User Manual, Release 12
For example, the URL used to connect to the Nextcloud server from the macOS Finder is:
https://example.com/nextcloud/remote.php/dav/files/USERNAME/
3. Click Connect.
The device connects to the server.
For added details about how to connect to an external server using macOS, check the vendor documentation .
Accessing Files Using Microsoft Windows
It is best to use a suitable WebDAV client from the WebDAV Project page .
If you must use the native Windows implementation, you can map Nextcloud to a new drive. Mapping to a drive
enables you to browse files stored on an Nextcloud server the way you would files stored in a mapped network drive.
Using this feature requires network connectivity. If you want to store your files offline, use the Desktop Client to sync
all files on your Nextcloud to one or more directories of your local hard drive.
Note: Prior to mapping your drive, you must permit the use of Basic Authentication in the Windows Registry. The
procedure is documented in KB841215 and differs between Windows XP/Server 2003 and Windows Vista/7. Please
4.2. Accessing Nextcloud Files Using WebDAV 23
Nextcloud User Manual, Release 12
follow the Knowledge Base article before proceeding, and follow the Vista instructions if you run Windows 7.
Mapping Drives With the Command Line
The following example shows how to map a drive using the command line. To map the drive:
1. Open a command prompt in Windows.
2. Enter the following line in the command prompt to map to the computer Z drive:
net use Z: https://<drive_path>/remote.php/dav/files/USERNAME/ /user:youruser
yourpassword
where <drive_path> is the URL to your Nextcloud server.
For example: net use Z: https://example.com/nextcloud/remote.php/dav/files/USERNAME/
/user:youruser yourpassword
The computer maps the files of your Nextcloud account to the drive letter Z.
Note: Though not recommended, you can also mount the Nextcloud server using HTTP, leaving the connection
unencrypted. If you plan to use HTTP connections on devices while in a public place, we strongly recommend using
a VPN tunnel to provide the necessary security.
An alternative command syntax is:
net use Z: \\example.com@ssl\nextcloud\remote.php\dav /user:youruser
yourpassword
Mapping Drives With Windows Explorer
To map a drive using the Microsoft Windows Explorer:
1. Migrate to your computer in Windows Explorer.
2. Right-click on Computer entry and select Map network drive... from the drop-down menu.
3. Choose a local network drive to which you want to map Nextcloud.
4. Specify the address to your Nextcloud instance, followed by /remote.php/dav/files/USERNAME/.
For example:
https://example.com/nextcloud/remote.php/dav/files/USERNAME/
Note: For SSL protected servers, check Reconnect at logon to ensure that the mapping is persistent upon subsequent
reboots. If you want to connect to the Nextcloud server as a different user, check Connect using different credentials.
5. Click the Finish button.
Windows Explorer maps the network drive, making your Nextcloud instance available.

Nextcloud User Manual, Release 12
Accessing Files Using Cyberduck
Cyberduck is an open source FTP and SFTP, WebDAV, OpenStack Swift, and Amazon S3 browser designed for file
transfers on macOS and Windows.
Note: This example uses Cyberduck version 4.2.1.
To use Cyberduck:
1. Specify a server without any leading protocol information. For example:
example.com
2. Specify the appropriate port. The port you choose depends on whether or not your Nextcloud server supports SSL.
Cyberduck requires that you select a different connection type if you plan to use SSL. For example:
80 (for WebDAV)
443 (for WebDAV (HTTPS/SSL))
3. Use the ‘More Options’ drop-down menu to add the rest of your WebDAV URL into the ‘Path’ field. For example:
remote.php/dav/files/USERNAME/
Now Cyberduck enables file access to the Nextcloud server.
Accessing public shares over WebDAV
Nextcloud provides the possibility to access public shares over WebDAV.
To access the public share, open:
4.2. Accessing Nextcloud Files Using WebDAV 25
Nextcloud User Manual, Release 12
https://example.com/nextcloud/public.php/dav
in a WebDAV client, use the share token as username and the (optional) share password as password.
Known Problems
Problem
Windows does not connect using HTTPS.
Solution 1
The Windows WebDAV Client might not support Server Name Indication (SNI) on encrypted connections. If you
encounter an error mounting an SSL-encrypted Nextcloud instance, contact your provider about assigning a dedicated
IP address for your SSL-based server.
Solution 2
The Windows WebDAV Client might not support TSLv1.1 / TSLv1.2 connections. If you have restricted your server
config to only provide TLSv1.1 and above the connection to your server might fail. Please refer to the WinHTTP
documentation for further information.
Problem
You receive the following error message: Error 0x800700DF: The file size exceeds the limit allowed and cannot
be saved.
Solution
Windows limits the maximum size a file transferred from or to a Web-
DAV share may have. You can increase the value FileSizeLimitInBytes in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters by clicking on
Modify.
To increase the limit to the maximum value of 4GB, select Decimal, enter a value of 4294967295, and reboot Windows
or restart the WebClient service.
Problem
Accessing your files from Microsoft Office via WebDAV fails.
Solution
Known problems and their solutions are documented in the KB2123563 article.
Problem
Cannot map Nextcloud as a WebDAV drive in Windows using self-signed certificate.
26 Chapter 4. Files & Synchronization

17. Close browser, then re-open and test.
Problem
You cannot download more than 50 MB or upload large Files when the upload takes longer than 30 minutes using Web
Client in Windows 7.
Solution
Workarounds are documented in the KB2668751 article.
Accessing Files Using cURL
Since WebDAV is an extension of HTTP cURL can be used to script file operations.
To create a folder with the current date as name:
$ curl -u user:pass -X MKCOL "https://example.com/nextcloud/remote.php/dav/files/USERNAME/$(date '+%d-%b-%Y')"
To upload a file error.log into that directory:
$ curl -u user:pass -T error.log "https://example.com/nextcloud/remote.php/dav/files/USERNAME/$(date '+%d-%b-%Y')/error.log"
To move a file:
4.2. Accessing Nextcloud Files Using WebDAV 27
Nextcloud User Manual, Release 12
$ curl -u user:pass -X MOVE --header 'Destination: https://example.com/nextcloud/remote.php/dav/files/USERNAME/target.jpg' https://example.com/nextcloud/remote.php/dav/files/USERNAME/source.jpg
To get the properties of files in the root folder:

sorting, zoom, and scrolling. It also supports advanced customizations via a simple text file.
On your main Nextcloud Files page, click the little icon at the top right, underneath your username, to open your
Gallery. The Gallery app automatically finds all images in your Nextcloud folders, and overlays the thumbnails with
the folder names. Click on the folder thumbnails to open the folders. At the top left you have two sorting options,
alphabetical and by date.
After entering any folder, click on any image to open it in slideshow mode. This has the following features: a download
button at the top center, forward and back buttons at the right and left sides, an automatic slideshow button at the bottom
right, and a close button at the top right.
Custom Configuration
You may customize a Gallery album with a simple text file named gallery.cnf, which contains parameters structured
using the Yaml markup language. You may have multiple gallery.cnf files; you need one in your own root Nextcloud

Setup
The configuration file has to be named gallery.cnf. You may have multiple per-album gallery.cnf files. To enable
global features, place one in your top-level folder, which is symbolised in the Web GUI by the home icon. (This puts
it in data/<user>/files/.) See an example below in the Global features section.
Note: You need to refresh your browser after changing your configuration to see your changes.
Format
UTF-8, without BOM. A file created from within the Nextcloud Web GUI works.
Structure
You should include a comment in the file, so that people stumbling upon the file know what it’s for. Comments start
with #.
Spacing is created using 2 spaces. Do not use tabs.
Take a look at the YAML Format documentation if you are getting error messages.
Here is an example gallery.cnf :

Supported Variables
Global Features
Place this in your root Nextcloud folder, which is your Home folder.
external_shares: Set to yes in your root configuration file if you want to load images stored on external loca-
tions, when using the files_external app.
4.3. Gallery App 31
Nextcloud User Manual, Release 12
native_svg: Set to yes in your root configuration file to enable rendering SVG images in your browser. This
may represent a security risk if you can’t fully trust your SVG files.
background_colour_toggle: Set to yes in your root configuration file to enable a button that toggles between
black and white backgrounds on transparent images.
Note: External shares are 20-50 times slower than local shares. Be prepared to wait a long time before being able to
see all the images contained in a shared album.
Album Configuration
Each album can be individually configured using the following configuration sections. Use the inherit parameter to
pass configurations on to sub-albums.
Design
background: Defines the colour of the background of the photowall using the RGB hexadecimal representation
of that colour. For example: “#ffa033”. You must use quotes around the value or it will be ignored. It is strongly
recommended to use a custom theme, with a CSS loading spinner if you intend to use this feature. You can use
this colour wheel to find a colour you like.
inherit: Set to yes if you want sub-folders to inherit this part of the configuration.
Album Presentation
description: A markdown-formatted string which will be displayed in the info box. It can spread over multiple
lines using the Yaml markers.
description_link: A markdown file located within the album which will be parsed and displayed in the info box
instead of the description.
copyright: A markdown-formatted string. This supports links to external resources.
copyright_link: Any file (e.g. copyright.html), in the album itself, which will be downloaded when the user
clicks on the link
inherit: Set to yes if you want sub-folders to inherit this part of the configuration.
See http://www.markitdown.net/markdown for the markdown syntax.
Note: Do not add links to your copyright string if you use the copyright_link variable.
Sorting
sorting:date or name.date only works for files.
sort_order:asc or des (Ascending or descending).
inherit: Set to yes if you want sub-folders to inherit this part of the configuration.
Notes
When only the sort type variable has been set, the default sort order will be used.
When only the sort order variable has been found, the sort configuration will be ignored and the script will keep
looking for a valid configuration in upper folders.
To enable a feature such as native SVG in a public share, you need to create in that folder a configuration file
containing that feature.
32 Chapter 4. Files & Synchronization
Nextcloud User Manual, Release 12
If you share a folder publicly, don’t forget to add all the files you link to (e.g. description.md or
copyright.md) inside the shared folder as the user won’t have access to files stored in the parent folder.
Since people can download a whole folder as an archive, it’s usually best to include all files within a shared
folder, rather than adding text directly in the configuration file.
Examples
Sorting Only

Nextcloud User Manual, Release 12
Managing Deleted Files
When you delete a file in Nextcloud, it is not immediately deleted permanently. Instead, it is moved into the trash bin.
It is not permanently deleted until you manually delete it, or when the Deleted Files app deletes it to make room for
new files.
Find your deleted files by clicking on the Deleted files button on the Files page of the Nextcloud Web interface. You’ll
have options to either restore or permanently delete files.
Quotas
Deleted files are not counted against your storage quota. Only your personal files count against your quota, not files
which were shared with you. (See Storage Quota to learn more about quotas.)
What Happens When Shared Files Are Deleted
Deleting files gets a little complicated when they are shared files, as this scenario illustrates:
1. User1 shares a folder “test” with User2 and User3
2. User2 (the recipient) deletes a file/folder “sub” inside of “test”
3. The folder “sub” will be moved to the trashbin of both User1 (owner) and User2 (recipient)
4. But User3 will not have a copy of “sub” in her trash bin
When User1 deletes “sub” then it is moved to User1’s trash bin. It is deleted from User2 and User3, but not placed in
their trash bins.
When you share files, other users may copy, rename, move, and share them with other people, just as they can for any
computer files; Nextcloud does not have magic powers to prevent this.
How the Deleted Files app Manages Storage Space
To ensure that users do not run over their storage quotas, the Deleted Files app allocates a maximum of 50% of their
currently available free space to deleted files. If your deleted files exceed this limit, Nextcloud deletes the oldest files
(files with the oldest timestamps from when they were deleted) until it meets the memory usage limit again.
Nextcloud checks the age of deleted files every time new files are added to the deleted files. By default,
deleted files stay in the trash bin for 180 days. The Nextcloud server administrator can adjust this value
in the config.php file by setting the trashbin_retention_obligation value. Files older than the
trashbin_retention_obligation value will be deleted permanently. Additionally, Nextcloud calculates
the maximum available space every time a new file is added. If the deleted files exceed the new maximum allowed
space Nextcloud will expire old deleted files until the limit is met once again.
Desktop and Mobile Synchronization
For synchronizing files with your desktop computer, we recommend using the Nextcloud Sync Client for Windows,
macOS and Linux.
The Nextcloud Desktop Sync Client enables you to connect to your Nextcloud Server. You can create folders in your
home directory, and keep the contents of those folders synced with your Nextcloud server. Simply copy a file into
the directory and the Nextcloud desktop client does the rest. Make a change to the files on one computer, it will flow
across the others using these desktop sync clients. You will always have your latest files with you wherever you are.
34 Chapter 4. Files & Synchronization
Nextcloud User Manual, Release 12
Its usage is documented separately in the Nextcloud/ownCloud Desktop Client Manual.
Mobile Clients
Visit your Personal page in your Nextcloud Web interface to find download links for Android and iOS mobile sync
clients. Or, visit the Nextcloud download page.
Visit the Nextcloud documentation page to read the user manuals.
Encrypting Your Nextcloud Files
Nextcloud includes an Encryption app, and when it is enabled by your Nextcloud administrator all of your Nextcloud
data files are automatically encrypted. Encryption is server-wide, so when it is enabled you cannot choose to keep
your files unencrypted. You don’t have to do anything special, as it uses your Nextcloud login as the password for
your unique private encryption key. Just log in and out and manage and share your files as you normally do, and you
can still change your password whenever you want.
Its main purpose is to encrypt files on remote storage services that are connected to your Nextcloud server, such as
Dropbox and Google Drive. This is an easy and seamless way to protect your files on remote storage. You can share
your remote files through Nextcloud in the usual way, however you cannot share your encrypted files directly from
Dropbox, Google Drive, or whatever remote service you are using, because the encryption keys are stored on your
Nextcloud server, and are never exposed to outside service providers.
If your Nextcloud server is not connected to any remote storage services, then it is better to use some other form
of encryption such as file-level or whole disk encryption. Because the keys are kept on your Nextcloud server, it is
possible for your Nextcloud admin to snoop in your files, and if the server is compromised the intruder may get access
to your files. (Read How Nextcloud uses encryption to protect your data to learn more.)
Encryption FAQ
How Can Encryption Be Disabled?
The only way to disable encryption is to run the “decrypt all”.
script, which decrypts all files and disables encryption.
Is It Possible To Disable Encryption With The Recovery Key?
Yes, if every user uses the file recovery key,“decrypt all” will use it to decrypt all files.
Can Encryption Be Disabled Without The User’s Password?
If you don’t have the users password or file recovery key.
then there is no way to decrypt all files. What’s more, running it on login would be dangerous, because you would
most likely run into timeouts.
Is It Planned To Move This To The Next User Login Or A Background Job?
If we did that, then we would need to store your login password in the database. This could be seen as a security issue,
so nothing like that is planned.
4.6. Encrypting Your Nextcloud Files 35
Nextcloud User Manual, Release 12
Is Group Sharing Possible With The Recovery Key?
If you mean adding users to groups and make it magically work? No. This only works with the master key.
Using Encryption
Nextcloud encryption is pretty much set it and forget it, but you have a few options you can use.
When your Nextcloud admin enables encryption for the first time, you must log out and then log back in to create your
encryption keys and encrypt your files. When encryption has been enabled on your Nextcloud server you will see a
yellow banner on your Files page warning you to log out and then log back in.
When you log back in it takes a few minutes to work, depending on how many files you have, and then you are returned
to your default Nextcloud page.
Note: You must never lose your Nextcloud password, because you will lose access to your files. Though there is
an optional recovery option that your Nextcloud administrator may enable; see the Recovery Key Password section
(below) to learn about this.
Sharing Encrypted Files
Only users who have private encryption keys have access to shared encrypted files and folders. Users who have not yet
created their private encryption keys will not have access to encrypted shared files; they will see folders and filenames,
but will not be able to open or download the files. They will see a yellow warning banner that says “Encryption App
is enabled but your keys are not initialized, please log-out and log-in again.
Share owners may need to re-share files after encryption is enabled; users trying to access the share will see a message
advising them to ask the share owner to re-share the file with them. For individual shares, un-share and re-share the
36 Chapter 4. Files & Synchronization
Nextcloud User Manual, Release 12
file. For group shares, share with any individuals who can’t access the share. This updates the encryption, and then
the share owner can remove the individual shares.
Recovery Key Password
If your Nextcloud administrator has enabled the recovery key feature, you can choose to use this feature for your
account. If you enable “Password recovery” the administrator can read your data with a special password. This feature
enables the administrator to recover your files in the event you lose your Nextcloud password. If the recovery key is
not enabled, then there is no way to restore your files if you lose your login password.
Files Not Encrypted
Only the data in your files is encrypted, and not the filenames or folder structures. These files are never encrypted:
Old files in the trash bin.
Image thumbnails from the Gallery app.
Previews from the Files app.
The search index from the full text search app.
Third-party app data
There may be other files that are not encrypted; only files that are exposed to third-party storage providers are guaran-
teed to be encrypted.
Change Private Key Password
This option is only available if your log-in password, but not your encryption password, was changed by your admin-
istrator. This can occur if your Nextcloud provider uses an external user back-end (for example, LDAP) and changed
your login password using that back-end configuration. In this case, you can set your encryption password to your new
login password by providing your old and new login password. The Encryption app works only if your login password
and your encryption password are identical.
4.6. Encrypting Your Nextcloud Files 37
Nextcloud User Manual, Release 12
Using Federation Shares
Federation Sharing allows you to mount file shares from remote Nextcloud servers, in effect creating your own cloud
of Nextclouds. You can create direct share links with users on other Nextcloud servers.
Creating a New Federation Share
Federation sharing is enabled on new or upgraded Nextcloud installations by default. Follow these steps to create a
new share with other Nextcloud or ownCloud 9+ servers:
1. Go to your Files page and click the Share icon on the file or directory you want to share. In the sidebar enter the
username and URL of the remote user in this form: <username>@<oc-server-url>. In this example, that is
layla@remote-server/nextcloud. The form automatically echoes the address that you type and labels it as
“remote”. Click on the label.
2. When your local Nextcloud server makes a successful connection with the remote Nextcloud server you’ll see a
confirmation. Your only share option is Can edit.
Click the Share button anytime to see who you have shared your file with. Remove your linked share anytime by
clicking the trash can icon. This only unlinks the share, and does not delete any files.
Creating a New Federated Cloud Share via Email
Use this method when you are sharing with users on ownCloud 8.x and older.
What if you do not know the username or URL? Then you can have Nextcloud create the link for you and email it to
your recipient.
When your recipient receives your email they will have to take a number of steps to complete the share link. First they
must open the link you sent them in a Web browser, and then click the Add to your Nextcloud button.
38 Chapter 4. Files & Synchronization
Nextcloud User Manual, Release 12
The Add to your Nextcloud button changes to a form field, and your recipient needs to enter the URL of their
Nextcloud or ownCloud server in this field and press the return key, or click the arrow.
Next, they will see a dialog asking to confirm. All they have to do is click the Add remote share button and they’re
finished.
Remove your linked share anytime by clicking the trash can icon. This only unlinks the share, and does not delete any
files.
Making Anonymous Uploads
You may create your own special upload directories so that other people can upload files to you without having to log
in to the server, and without being an Nextcloud user. They will not be allowed to see the contents of this directory, or
to make any changes. This is an excellent alternative to sending large attachments via email, using an FTP server, or
using commercial file-sharing services.
Setting Up Your Own File Drop
Go to Files and create or choose the folder, the anonymous upload should be made to.
Check Share Link, Allow editing, Hide file listing.
4.8. Making Anonymous Uploads 39
Nextcloud User Manual, Release 12
Now you can send the link to the upload folder manually or by using the Nextcloud send function, if your administrator
has enabled it.
Uploading Files
Using the anonymous upload function is simple. You receive a link to the upload folder, click the link, and then you’ll
see an Nextcloud page with a Click to upload button.
40 Chapter 4. Files & Synchronization
Nextcloud User Manual, Release 12
This opens a file picker, and you select the file or directory you want to upload. You’re also able to just drop files into
the window.
When your upload is completed, the filenames are listed:
Large File Uploads
When uploading files through the web client, Nextcloud is limited by PHP and Apache configurations. By default,
PHP is configured for only 2 megabyte uploads. As this default upload limit is not entirely useful, we recommend that
your Nextcloud admin increase the Nextcloud variables to sizes appropriate for users.
Modifying certain Nextcloud variables requires administrative access. If you require larger upload limits than have
been provided by the default (or already set by your administrator):
Contact your administrator to request an increase in these variables
Refer to the section in the Admin Documentation that describes how to manage file upload size limits.
Storage Quota
Your Nextcloud admin has the option to set a storage quota on users. Look at the top of your Personal page to see
what your quota is, and how much you have used.
It may be helpful to understand how your quota is calculated.
4.9. Large File Uploads 41
Nextcloud User Manual, Release 12
Metadata (thumbnails, temporary files, cache, and encryption keys) takes up about 10% of disk space, but is not
counted against user quotas. Some apps store information in the database, such as the Calendar and Contacts apps.
This data is excluded from your quota.
When other users share files with you, the shared files count against the original share owner’s quota. When you share
a folder and allow other users or groups to upload files to it, all uploaded and edited files count against your quota.
When you re-share files shared with you, the re-share still counts against the quota of the original share owner.
Encrypted files are a little larger than unencrypted files; the unencrypted size is calculated against your quota.
Deleted files that are still in the trash bin do not count against quotas. The trash bin is set at 50% of quota. Deleted
file aging is set at 30 days. When deleted files exceed 50% of quota then the oldest files are removed until the total is
below 50%.
When version control is enabled, the older file versions are not counted against quotas.
If you create a public share via URL, and allow uploads, any uploaded files count against your quota.
Version Control
Nextcloud supports simple version control system for files. Versioning creates backups of files which are accessible
via the Versions tab on the Details sidebar. This tab contains the history of the file where you can roll back a file to
any previous version. Changes made at intervals greater than two minutes are saved in data/[user]/versions.
To restore a specific version of a file, click the circular arrow to the left. Click on the timestamp to download it.
The versioning app expires old versions automatically to make sure that the user doesn’t run out of space. This pattern
is used to delete old versions:
For the first second we keep one version
For the first 10 seconds Nextcloud keeps one version every 2 seconds
For the first minute Nextcloud keeps one version every 10 seconds
For the first hour Nextcloud keeps one version every minute
For the first 24 hours Nextcloud keeps one version every hour
For the first 30 days Nextcloud keeps one version every day
After the first 30 days Nextcloud keeps one version every week
42 Chapter 4. Files & Synchronization
Nextcloud User Manual, Release 12
The versions are adjusted along this pattern every time a new version gets created.
The version app never uses more that 50% of the user’s currently available free space. If the stored versions exceed
this limit, Nextcloud deletes the oldest versions until it meets the disk space limit again.

USING TWO-FACTOR AUTHENTICATION
Two-factor authentication (2FA) is a way to protect your Nextcloud account against unauthorized access. It works by
requiring two different ‘proofs’ of your identity. For example, something you know (like a password) and something
you have like a physical key. Typically, the first factor is a password like you already have and the second can be a
text message you receive or a code you generate on your phone or another device (something you have). Nextcloud
supports a variety of 2nd factors and more can be added.
Once a two-factor authentication app has been enabled by your administrator you can enable and configure it in Setting
Your Preferences. Below you can see how.
Configuring two-factor authentication
In your Personal Settings look up the Second-factor Auth setting. In this example this is TOTP, a Google Authenticator
compatible time based code.
You will see your secret and a QR code which can be scanned by the TOTP app on your phone (or another device).
Depending on the app or tool, type in the code or scan the QR and your device will show a login code which changes
every 30 seconds.
Recovery codes in case you lost your 2nd factor
You should always generate backup codes for 2FA. If your 2nd factor device gets stolen or is not working, you will
be able to use one of these codes to unlock your account. It effectively functions as a backup 2nd factor. To get the
backup codes, go to your Personal Settings and look under Second-factor Auth settings. Choose Generate backup
codes.
You will then be presented with a list of one-time-use backup codes.
You should put these codes in a safe spot, somewhere you can find them. Don’t put them together with your 2nd factor
like your mobile phone but make sure that if you lose one, you still have the other. Keeping them at home is probably
the best thing to do.
Logging in with two-factor authentication
After you have logged out and need to log in again, you will see a request to enter the TOTP code in your browser.
Just enter your code:
If the code was correct you will be redirected to your Nextcloud account.

Note: Since the code is time-based, it’s important that your server’s and your smartphone’s clock are almost in sync.
A time drift of a few seconds won’t be a problem.
Using client applications with two-factor authentication
Once you have enabled 2FA, your clients will no longer be able to connect with just your password unless they also
have support for two-factor authentication. To solve this, you should generate device specific passwords for them. See
Manage Connected Browsers and Devices for more information on how to do this.

MANAGE CONNECTED BROWSERS AND DEVICES
The personal settings page allows you to have an overview on the connected browsers and devices.
Managing Connected Browsers
In the list of connected browsers you see which browsers connected to your account recently:
You can use the trash icon to disconnect any of the browsers in the list.

Managing Devices
In the list of connected devices you see all the devices and clients you generated a device password for and their last
activity:
You can use the trash icon to disconnect any of the devices in the list.
At the bottom of the list you find a button to create a new device-specific password. You can choose a name to identify
the token later. The generated password is used for configuring the new client. Ideally, generate individual tokens for
every device you connect to your account, so you can disconnect those individually if necessary.
Note: You have only access to the device password when creating it, Nextcloud will not save the plain password,
hence it’s recommended to enter the password on the new client immediately.
Note: If you are Using two-factor authentication for your account, device-specific passwords are the only way to
configure clients. The client will deny connections of clients using your login password then.

EXTERNAL STORAGE
Configuring External Storage
The External Storage application allows you to mount external storage services, such as Google Drive, Dropbox,
Amazon S3, SMB/CIFS fileservers, and FTP servers in Nextcloud. Your Nextcloud server administrator controls
which of these are available to you. Please see Configuring External Storage (GUI) in the Nextcloud Administrator’s
manual for configuration howtos and examples.
